What is the calorie requirement and how is it calculated?

This article will explain what the calorie requirement is and how it is calculated


What does the energy needs consist of?

Your energy requirement is the number of calories that your body needs every day to survive. It is made up of the basal metabolic rate and your physical activity.


What is the basal metabolic rate?

Your basal metabolic rate (BMR) is the energy that your body requires for various basic functions and processes in a state of rest. Even if you lay in bed all day and didn’t do anything at all, your body uses up energy for digestion, your heartbeat, and maintaining your body temperature. The BMR depends on your biological gender, your body height, your body weight, and your age. Men, for example, inherently have about 10% more muscle mass than women and, thus, a higher BMR. Also, a tall individual burns more calories than a shorter individual in a state of complete rest. With increasing age, our calorie requirement decreases due to the fact that we lose muscle mass as part of the natural aging process.


What is the power metabolic rate?

Since your body isn’t in a state of rest all day, it also burns energy through physical activity in addition to your basal metabolic rate. As a result, individuals who work hard physically or do lots of sports have a higher calorie requirement than those who work in an office, for example.

Thus, you can directly influence the amount of energy your body burns by increasing your physical activity.


How does YAZIO calculate the basal metabolic rate?

We calculate your BMR with the help of the Mifflin St Jeor equation. This formula takes the overall lifestyle changes of the past centuries into account and is up to 5% more accurate than other formulas. This equation considers your height, weight, biological gender, and age. To determine the number of calories burned through an activity we multiply your BMR with a so-called physical activity level (PAL), which can be anything from 1.2 (in a state of rest) up to 2.4 in the case of intense physical activity.

We’re continuously working on improving YAZIO to fit your personal needs even better. Nonetheless, there are certain limits in calculating every person’s individual energy requirement.


Can the individual metabolism be taken into account in the calculation?

Our equation unfortunately cannot take into account the fact that every metabolism is different. Besides body height, weight, gender, and activity level, there are other factors such as genetic predisposition, hormones, and the gut flora that can play an important role when determining your exact calorie requirement.

Should you notice that you’re not making any progress while following our recommendations, you also have the possibility to manually adjust your calorie and macronutrient goals.

However, if you have any doubts or questions, we recommend talking to a doctor or nutritionist first.

We hope that you were able to find answers to all your questions and wish you a great journey with YAZIO. Should you have any more questions, please feel free to contact our support team and submit your request here.
